The Jump Artist by Austin Ratner

Austria, 1928. A young man stands unjustly accused of murdering
his father. Albert Einstein and Thomas Mann speak out on his
behalf. Sigmund Freud is called to testify. The trial that ensues
sends shock waves throughout Europe. In this crucible of injustice,
one of the greatest artists of the 20th century is formed. Ratner's
novel re-creates the true story of Philippe Halsman, a photographer
whose portraits of some of the great names of our time ensured his
enduring fame, but whose renown masked a shocking tragedy.
